M ETALLIC ROOFING-Tl LE.

SPECIFICATION forming part of Letters Patent No. 503,173, dated August15, 1893.

Application filed July 11,1892. Serial No. 439,736. (No modal.)

To all whom it may concern:

Be it known that I, ADAM A. SPAHMEE, J r., of Philadelphia, in thecounty of Philadelphia, State of Pennsylvania, have invented certain newand useful Improvements in Metallic Roofing-Tiles, of which thefollowing is a specification, due reference being had to theaccompanying drawings, which form part hereof.

Myinvention relates to the construction of what are generally known asmetallic shingles for rooting; these shingles consisting of smallmetallic plates adapted to be secured to the boarding of a roof bynailing in the same way as wooden shingles or slates.

The object of my invention is to provide a lock-joint for such shingles,wherebyeach shingle can be locked on two or all four of its sides orends to like neighboring shingles in such a manner as to effectuallyprevent the entrance of water through the joints onto the boarding ofthe roof.

Reference being now had to the drawings which illustrate my inventionFigure l is a perspective view of a numberof myimproved shingles asapplied to a roof, each shingle shown constructed to lock down on allfour of its side edges. Fig. 2 is a View taken on the line -oc Fig. l,and showing two of my shingies interlocked and secured to the roofboarding. Fig. 3 is a detail view of a cornerof one of my platesdesigned to be locked down on all four of its side edges, showing itsoutline prior to being bent or shaped to form locking edges, and Fig. 4is an under perspective view of the corner X, Fig. l, and for anillustration of the opposite cornerY, the dotted lines represent theupper nailing iiange.

Referring to the drawings in which the parts are indicated by numerals,similar nnmerals denoting like parts,fl, l", lxx, are my improvedshingles, the opposite edges of which are bent or shaped as shown at'2,and 3. The edge 2 of my shingle is bent or shaped to the U-form 2X bydoubling the metal upon itself in the manner best shown in Fig. 2, andthe sheet is then carried outward on the plane of the main surface l,adistance sufficient to form a nailing iiange 4. The edge 3 of myshingle is also bent or shaped to a U-form in all respects similar toits opposite edge, without the nailing ange,the ends of the U beingaligned or nearly so.

5 represents the supporting boards to which the shingles are nailed.

6,is a nail for securing the nailing iiange 4 to the support, while7 isthe usual projection formed in the bottom of the center of each shingleto accommodate the elevated seam of the neighboring shingles, and allowthe upper plates to closely hug the lower ones.

In laying my shingles, theleft hand shingle (Fig. 2) is irstsecured tothe roof by the nailing fiange 4. The U-end 3 of the next shingle to theright is then interlocked with the U-end 2 of the left hand shingle bysimply forcing the parts together as shown in Fig. 2, to form a double-Ulock seam,and by reason of such construction the parts hug each other.so well and tightly as to effectually prevent the entrance of Waterthrough the joints.

' It will be obvious that' rooting plates or shingles embodying myinvention maybe constructed to lock down on two opposite sides only, oron all four sides if desiredg-in the latter case the cutting of themetal at each corner to the double right angle, as shown at Q- Fig. 3,prevents in construction or Working the-metal the meeting seams in asingle plate or shingle crossing each other,provides a free aandindependent locking edge, and avoids the excessive thickness of met-althat would otherwise be resultant, and other atprevent the entrance ofwateronto the board-` ing of the roof.

Having now described my invention, I claiml. A metallic rooing plate orshingle having one edge bent, shaped or formed to sub- 2. A rectangularshaped metallic roofing' plate or shingle its four edges formed tosubstantially a U-shape on the same side of the plate and on the sameplane with the body portion thereof; two adjacent edges of the samehaving nailing flanges extending away from and on the saine plane withthe body portion ot the plate or shingle, said nailing flanges beingacontinuation or integral portion of the metal forming their respectiveU- edge, the whole as constructed adapted to lock down on all four sideswith similar plates or i shingles, as shown and described.

3. The method of making metallic roofing plates or shingles having theirfour edges formed to substantially a U -shapc on the same side of theplate and on the sanne planewith the body portion thereof, two adjacentedges of the same having nailing flanges extending away from and on thesame plane with the body portion of the plate or shingle, said nailingflanges being a continuation or integral portion of the plate blankforming their respective U-edge, and so as to lock down on all foursides with similar plates or shingles, which consists in irst cuttingout the respective four corners of the metal blank to the double rightangle Q, and then twice doubling the respective edges of the blank uponitself to substantially a U shape, two adjacent corners of the metalblank having a deeper cut than the neighboring corners thereby providingfor two adjacent nailing flanges, substantially as described.

In testimony whereof I have hereunto signed my naine this 10th day ofSeptember, A. D. 1890.
